I got in on this one late, so I missed the original message, but I can
at least recommend a new supply. I have bought two Antec power supplies
at Fry's and have been happy with them both. They are quiet, and the
most recent one I bought had detachable cables so you don't have to
clutter up the inside of your case. They are not the cheapest, though.
I don't think they go for less than $50-60. The last one I bought was
on sale for $70, which was $20 off the regular price.
